It is defined as a FLOP per Byte ratio (F/B). Arithmetic intensity is a characteristic of the computational algorithm. In general, the processor frequency [capping][3] has low performance impact for memory bound computations (arithmetic intensity below the [ridge point][2]). For processor bound computations (arithmetic intensity above the [ridge point][2]), the impact is proportional to the frequency reduction. -- GitLab
